A block weighing 200N rests on a horizontal floor. A horizontal force P=100N directed to the right is applied to the bloxk and it reaches a velocity of 12m/sec in 40 m distance starting from rest. What is the coefficient of friction between the block and the floor?
Don't use chatgpt. I need handwritten solution with free body diagram.
Problem 1 The 2 blocks are originally at rest. The pulleys are smooth. The coefficient of friction between the block A and the incline are us = 0.35 and uK = 0.32. The mass of the blocks are ma = 50kg and MB = 80kg and the angle of the slope a = 35 degrees. %3D A 1. Find the relation between the acceleration of the block A and the block B 2. Do FBD and kinetic diagram of both blocks. 3. Solve for both accelerations, what is the direction of the motion? 4. Find the tension in the cable.
A small block (2.25kg) travels along a frictionless path at a speed (6m/s) before it reaches a frictionless semi circular path with a radius of 0.5m. 1) at point A, what is the force exerted by the track on the block? 2) the bottom of the track has a length of 15m with friction. Determine the coefficient of kinetic friction between the block and the bottom of the portion of the track if the block just makes it to point B before coming to rest.
2 A winch, located at M, pulls box A up an incline with a cable. The distance from the box to the winch is s. Suppose that, starting from rest, the box travels the full distance s with constant acceleration in T seconds. Assume the box has mass m and a sliding coefficient of friction of µk. Determine the tension in the cable, P. (Hint: Use 1D kinematics to find the acceleration.) Values: g = 9.81 m/s², 0 = 30 deg., m = 20 kg, T = 3 sec., s = 6 m, μk = 0.3 Problem Last Updated: September 23, 2023 Box A 1 of 3 8 Winch M
